Groundwater Remediation Consulting

On sites where contamination has occurred in the soil, it is common to also see impacts in the groundwater. In fact, there may be groundwater impacts even where the soil meets applicable regulations or allowable limits.

Groundwater remediation begins with understanding the scope and nature of the contamination. The environmental team will identify the contaminants of concern as part of a Phase II ESA or other investigation and will begin to characterize them through laboratory testing. This will include installing one or more groundwater monitoring wells in areas that are likely to have impacts in the groundwater.

Groundwater wells must be left for 24-48 hours in order to recharge after being installed. One of AEL’s environmental scientists will revisit the site to take samples which are submitted to a laboratory for analysis. The groundwater is tested for a range of parameters like metals, PHCs, PCBs, and other contaminants of concern, based on site history.

Once the nature of the groundwater contamination is understood, the environmental engineer will determine an appropriate method of remediating the groundwater impacts. This may include:

pumping and treating the groundwater in large storage containers on site

pumping and disposing of the groundwater

placing barriers on the site to prevent contaminants from migrating off-site through the groundwater

treating the impacts in-situ

The approach chosen will depend on the nature of the site and the specific characteristics of the impacted groundwater. An environmental engineer who is registered as a Qualified Person (QP) under O. Reg. 153/04, can work with you to determine the best approach for your site.

AEL environment understands that groundwater remediation strategies need to be tailored to the unique site and the site owner’s goals. Our team of QPs, remediation experts, environmental engineers, and scientists are able to help you to understand the regulations and what steps will help you to manage your environmental risk. Understanding how to limit your liability is an important step for every site owner and will allow you to make informed decisions with confidence.
